Programming tips
If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
Check the frequency of hand-held remote
R
control (typically located on the reverse
5
side of the remote). The integrated remote
240
control is compatible with radio-frequency
devices operating between 280-390 MHz.
Put a new battery in hand-held remote
R
control 5. This will increase the likelihood
of the hand-held remote control sending a
faster and more accurate signal to the
integrated remote control.
While performing step 3, hold hand-held
R
remote control at different lengths and
5
angles from the signal transmitter button
(2, or 4) you are programming.
3
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
If another hand-held remote control is
R
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
Straighten the antenna wire from the
R
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
